Side plank

The side of the trunk and the outside of the hip.

You need
Floor space.
Why it is in the plan
Keeps the trunk from folding sideways when you land on one leg or carry a pack. Short holds done well are enough.

How to do it

  1. 1Lie on your side with the elbow directly under the shoulder, legs straight and stacked.
  2. 2Lift the hips so ankle, hip and shoulder make a straight line.
  3. 3Hold and breathe normally.
  4. 4Come down before the hips sag. Switch sides.

Easier

Knees bent and resting on the floor.

Harder

Lift the top leg, or hold longer — up to about 45 seconds.

Common mistake

Hips sagging toward the floor or pushed back. When the line goes, the set is over.
